Measures of Central Tendency & Box and Whisker Plot Review

Front

What is the definition of Measures of Central Tendency?

Back

Measures of Central Tendency are statistical measures that describe the center or typical value of a dataset, commonly represented by the mean, median, and mode.

Front

What is the mean?

Back

The mean is the average of a set of numbers, calculated by adding all the values together and dividing by the number of values.

Front

What is the median?

Back

The median is the middle value of a dataset when the numbers are arranged in ascending order. If there are two middle numbers, the median is the average of those two.

Front

What is the mode?

Back

The mode is the value that appears most frequently in a dataset.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the smallest value from the largest value in the dataset.

Front

What is a Box and Whisker Plot?

Back

A Box and Whisker Plot is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, and maximum.

Front

What does the box in a Box and Whisker Plot represent?

Back

The box represents the interquartile range (IQR), which contains the middle 50% of the data.

Front

What do the whiskers in a Box and Whisker Plot indicate?

Back

The whiskers extend from the box to the smallest and largest values that are not outliers.

Front

How do you find the median of a dataset with an odd number of values?

Back

To find the median, arrange the numbers in order and select the middle number.

Front

How do you find the median of a dataset with an even number of values?

Back

To find the median, arrange the numbers in order and average the two middle numbers.
